/* Kraftrs Promotions — Offers Rail
 * A sticky edge tab (desktop: vertical text tab mid-screen; mobile: same tab,
 * panel becomes a bottom sheet) listing every active campaign opted in via
 * "Show in Offers Rail". Off by default (kp_offers_rail_enabled).
 *
 * Color customization: --kp-rail-color / --kp-rail-text-color are set inline
 * per-site (OffersRail::render_placeholder()) only when the merchant picked
 * a custom color; otherwise they fall through to the shared brand color
 * (--kp-primary) so the rail matches everything else out of the box.
